The Bond star explained there was an incredibly tense moment as she watched the biopic with the Mandela family for the first time.

"They were all at the South African premiere... there was silence throughout the film.

"I thought 'oh my gosh they don't like it' and then at the end one of Mandela's nieces was in my arms sobbing and Winnie's daughter was in tears," the Bond star said.

She added: "I realised they were processing it on a really profound level. It was not just a movie or a piece of history, it's their lives represented up there. If you capture it right, you force them to relive it and come to terms with things they hadn't come to terms with."
